insertibleinto a suitable pocket usually providedon the inside of the back cover of a book, the supplement orpamphlet being maintained by the attached cardboard back in position to permit convenient examination thereof.

The customary practice in making such pocket supplements has been to cut the cardboard back to the final desired configuration to enable its ready insertion into the pocket of the book, then to gather the several sections of pages or sheets that are to comprise the supplement and trim them while loose from one another along their outer and end edges. and finally to gather the pages'or sheets with the cardboard back and secure them together along their respective inner side edges.

The object of the present invention is to reduce the cost of production and also to afford a better finished product by proceeding in such a manner that the cardboard back may be attached to the several pages or sheets before trimming the latter, thus eliminating one gathering operation, and also resulting in greater uniformity of the cut edges of the cardboard back and printed pages owing to their all being trimmed simultaneously while secured together.

The cardboard back used in the making of-a pocket supplement is cut away at the ends of the outer edge along diagonal lines to afford a generally tapered configuration that permits ready insertion into the book pocket, and the invention, in its general aspect, consists in providing a rectangular cardboard back with diagonal cuts defining the desired triangular corner portions, such cuts extending to points slightly spaced from the outer side and end edges of the back whereby the separable corner portions remain attached to the body of the back while the latter is secured to the sections of pages or sheets and also during the trimming operation, and when the pile is trimmed along the outer side and end edges to separate the several pages of each folded sheet, the cuts are along lines that intersect the previously formed diagonal cuts in the back, thus Cal freeing the triangular corner portions from the body of the back.

By this procedure, the cardboard back and the attached pages of the pile are of uniform thickness throughout the line of cut of the trimming knife, resulting in uniform and smoothly cut edges. When the triangular corner portions are initially cut away'from the cardboard back, as in the conventional procedureheretofore, it is necessary to trim the sections of pages or sheets be- *5 fore attaching the cardboard back, because if trimmed after attachment, the edges of the pages would, be jagged and irregularly cut owing to the fact that at one part of the cut, a portion of the cardboard back is under the trimming knife whereas at another portion ofthe cut the cardboard back is cut away, causing a variation in the thickness of material presented to the knife and a corresponding irregularity in the resistance of the massto the knife. To trim successfully, a pile of stock must be of uniform thickness throughout the path of the knife, and it is for this reason that heretofore, the trimmingoperation has taken place before attachment of the cardboard back to the printed pages.

To these and other ends, the invention consists in the steps or procedure that will appear from the following description when read in conjunction with the accompanying drawing, the novel features being pointed out in the claims following the specification.

In the drawing:

Fig. 1 is a plan View of a pocket supplement made in accordance with the invention;

Fig. 2 is a plan View of the cardboard back before attachment to the printed sections, and

Fig. 3 is a plan view showing the cardboard back attached to the several sections, and before trimming. 1

Referring more particularly to the drawing in which like reference characters refer to the same parts throughout the several views, the completed supplement is illustrated in Fig. l, in which I designates the cardboard back, cut away along the diagonal lines 2 at the ends of its outer edge and secured'at 3 along its inner edge by staples or otherwise to the printed pages or sheets 4.

According to the practice heretofore, the cardboard back I is initially out to the configuration illustrated in Fig. 1 with its outer corner portions cut away on the diagonal lines 2. The printed pages or sheets 4 are gathered and trimmed along their outer side and end edges before attaching the back I and while loose from one another, and after completion of the trim- 50 ming operation, the back i is gathered with the printed pages or sheets and stapled or otherwise attached thereto.

According to the present method, a rectangu lar cardboard back 5, see Fig. 2, is out along the 55 diagonal lines 6, the cuts 6 extending to points slightly spaced from the side and end edges of theback, and leaving suflicient material to hold the corner portion attached to the body of the back'until it is entirely severed during the trimming operation.

The back, out as shown in Fig. 2, or otherwise formed-with the separablecorner portions connected. to and carried by the body of the back, is thenrgathered witha series of printed pages or sheets, or what-are sometimes commercially termed signatures, and permanently attached thereto along its inner side edge "by the staples l,

I or other suitable instrumentalities.

.Following the stapling operation, the assembly is trimmed in a'suitable trimming machine along the lines indicated at 8 and 9 respectively, which are parallel to the outer side and end edges of the back; and intersect the diagonal cuts B,as'

shown. This trimming operation serves to separate the folded pages at their edges to permit independent turning; as usual in the opera'tion of trimming a pile of printed folded sections, and at the same time entirely severs the corner portions of the cardboard back from the body there% of; owing to the trimming cuts intersecting or extending crosswise of'the previously formed di- 'agonal cuts,6'inl the back. 1 The corner portions of the back can then ran away fromthe body and the completed structure appears as illustrated in Fig. l, with the cardboard back ready for ing sertion into a. pocket of a book.

is insertible into a book pocket, which consists in cutting a rectangular back along diagonal lines extending between its outer side edge and its end edges, said cuts terminating at points spaced from said outer side and end edges, se-

curing the back along its inner side edge to a section of pages, and thereafter trimming the pages andlback' along lines parallel to its outer side and end edges and intersecting said diagonal cuts in the back. 7
